Fig. Sis anend elevation thereof, the devices for connecting the needle-bars withtheir actuating-levers, and also the mechanism for actuating thepattern-wheel being 0 omitted in order to avoid confusion and to betterillustrate the features shown in this figure. Figs. 9 and 10 are viewsof details.

Like letters of reference indicate corresponding parts in the differentfigures of the 5 drawings.

My invention relates more especially to that class of looms which aredesigned for manufacturing-figured or ornamental elastic fabrics-such assuspender-webbing, and also 0 ribbons, tapes, and narrow goodsgenerally.

The nature and operation of my improvement will be readily understood byall conversant with such matters from the following explanation, it notbeing deemed essential to show all parts of the loom in order toillustrate the invention. In the drawings, A represents the lathe, B Bthe pendnlous arms by which the same is suspended, G a shuttle, D theshuttle-race,-and E a section of reed, these parts being all of theordinary form andoonstruction. Projecting upwardly from the lathe thereare two stand ards, F F, and fitted to work vertically in a suitableslot in either of said standards there is aslide or box, :0. Twohorizontally-arranged 5 5 bars-or needle-holders, H .l, are fitted toslidelongitudinally in the boxes at, the lower bar,

J, carrying two vertically-arranged eye-pointed needles, m, and thesuperposed bar H two corresponding needles, (I. A coiled-spring, K, isattached to each of the bars or holders H J, one end of the spring beingsecured to the bar and the other to one of the pendnlous arms B, thesprings acting contractively to force the bars constantly in thedirection of the pattern-wheel, as hereinafter more fully described. AU-shaped clamp, Z, is passed from front to rear over the bars H J, whichbars slide freely through the same, and pivoted in the projecting endsof said clamp on the rod d at the rear of said bars there are tworatchet pawls, z, said pawls being respectively adapted to engage teeth1; on said bars, and provided with canrshaped projections i, and curvedarms or tail-pieces r. The rod d is fixed at 7 its upper end in theclamp l, and slides freely at its lower end in the socket f which latteris pivoted on afixed portion of the lathe and adapted to oscillateslightly to permit the lateral movement of the rod (1. The rod d isloose in said socket, whereby the clamp l is permitted to rise and fallwith the rods H J.

A bell-crank lever,L, is pivoted at t to the rear portion of the latheA, the vertical arm of said lever being adapted to engage the tail- 8 5pieces 9" of the pawls z, and its horizontal arm provided with avertically-arranged rod, k, for a purpose hereinafter set forth.

Projecting upwardly from one end of the lathe A there is a standard, M,provided with go a slot, 7), in which a slide or box, N, is fitted towork vertically.- This slide is provided with a fixedhorizontally-arranged stub-shaft,

f, and a two-armed bracket, 0. A ratchetwheel, P, and pattern-wheel Qare journaled 5 on the stub-shaft f, and pivoted to one of the arms ofthe bracket 0 there is a retainingpawl, 9, adapted to engage the wheelP. A bar or lever, R, has its lower end. pivoted to the shaft f, and itsupper end providedwith zoo a rod, 19, said rod having a loop or slot, in

its lower end, in which the headed stud or wrist-pin 0 works. Anactuating-pawl, 4%, adapted to engage the ratchet-wheel P, is pivoted tothe lever B by means of the bolt g, which passes through a slot, to, insaid leverand is made adjustable therein by a nut screwed onto its bodyat the other side of the lever. One of the arms of the bracket 0 isprovided with an adj nsting-screw, y, adapted to engage the lever It andprevent it from falling too low when it is depressed in actuating theratchet-wheel P, said wheel being attached to the wheel Q in such amanner as to cause them to revolve conjointly. A red, S, has its lowerend secured to the slide or box N, said rod being employed in raisingand lowering said box, and the wheels P Q, bracket 0, lever B, and pawlsg a, conjointly or in unison with the needle-holding bars H J, a rod,'1, being secured to each of the boxes 00, for raising and lowering saidbars. A double row of pins.

-a, project laterally from the wheel Q, said pins being constructed ofunequal lengths, or in accordance with the pattern to be followed inornamenting the web, the inner row of pins being adapted to engage theend of the bar H, and the outer row the end of the bar J. The main frame1 supports in suitable bearings a shaft, 2, to which motion iscommunicated from a source of power. The shaft 2 carries a gear-wheel,3, which meshes with another gear-wheel, 4, the shaft of which carries acrank. A rod, 5, connectsv this crank with the lathe A, andreciprocatory motion is thus imparted to the latter in a well-knownmanner. The shaft 2 also carries a numberof cams, 6, having suitablefaces for the work they are designed to perform, and pivoted in the mainframe 1 are levers ,7 provided near their free ends with friction-rollers adapted to bear upon said camfaces. A rock-shaft, 8, hasits bearings also in said main frame, near the top thereof, and aslotted arm, 9, extends to the rear of said shaft. A rod, 10, connectssaid arm 9 with one of said levers 7, and oscillatory motion is therebyimparted to said shaft 8. Slot ted arms 11 project to the front of saidshaft, to which the rods T T and S are attached, whereby at everyrevolution of the cam 6 the rods H J and pattern-wheel Q, with theiraccompanying mechanism, are twice raised and lowered.

Upon an extension, 12, of the main frame 1 are pivoted bell-cranksarranged in pairs 13 13 and 43 4-3, the members of said pairs beingconnected by rods 1) and k, respectively. Rodsp and k connect one memberof each pair with separate cam-levers 7, and rods 19 and It at the otherend of the frame connectthe other members of said pairs with the leversR and L, respectively, whereby at proper intervals the rods H J areshifted laterally, and the pawl n operates the ratchet-wheel P, all ashereinafter described. The web Uis ornamented by means of threads 0,which pass from spools (not shown) mounted on the loom through theguides at and thence respectively through the eyes the web.

Guards m are employed to prevent the needles d on from being sprung ordrawn out of proper position by the strain on the threads 0 during theprocess of incorporating said threads in the web. These guards consist,respectively, of rigid wires or rods arranged horizontally in front ofthe needles near the upper portion of the reed E andfirmly secured ateither end to a fixed portion of the lathe or shuttle race in such amanner that when a needle is bent a trifle outwardly or toward the frontof the lathe by the action of its thread it will strike one of theguards, the vertical movements of the needle not being interfered withthereby. The needles work vertically and pass through the unfilledwarpthreads between the path or race of the shuttle O, the reed E, thepattern-wheel and nee dles swinging with the lathe A. Lateral movementsof'the needles in one direction or to the left are caused by drawing upthe horizontal arm of the lever L by means of the rod k, therebybringing the vertical arm of said lever into contact with theprojections i on the pawls z and causing said pawls toengage the teeth aand slide the bars or holders H J to the left, the reverse lateralmovement of the needles to the right being caused by the action of thesprings K when the vertical arm of the lever L is withdrawn from theprojection 12 by depressing the rod k. The clamp l is of the needles rimand into returned to its normal position after the vertical arm ofthelever L is withdrawn by means of the springs 9, its movement towardthe right being arrested by the stop 9 which de termines the oscillationof the socket 1. When the vertical arm of the lever L is withdrawn fromthe projections on the pawls z, and strikes the curved arms 1' of saidpawls, the pawls are thereby disengaged from the teeth 1) on thebars orholders H J, permitting said bars to be forced by the springs K againsttheir respective pins in the wheel Q; but as said pins are of unequallengths one of the bars will travel toward the right a greater distancethan the other, thus changing the relative position of the needles d mwith respect to the web E. It will be obvious, however, that when thevertical arm of the lever L strikes the projections i on the pawls zboth of said pawls will be caused to engage the bars simultaneously andboth of said bars moved in unison to the left.

In order to more clearly understand the method of incorporating thethreads 0 in the web U, and thereby ornamenting the same, I willdescribe the operation of the principal parts shown during one fullrevolution of the main driving-wheel of the loom, or one completetraverse of the lathe. The lathe being at the front of the loom, theshuttle at the right IIO hand side of the web, and the needles,needlebars, and pattern-wheel elevated,with the needles threaded, andsaid bars against their respective pins in the pattern-wheel, if, now,the

loom is started up the lathe will be moved or swung back from thebreast-beam, and at the first quarter of its traverse the needles,needie-bars, and pattern-wheel will be lowered, and the needles carryingtheir threads will pass through the warp-threads and remain down whilethe lathe passes through the second and third quarters of its traverse.After the lathe has passed through the first quarter of its traverse,and while it is making its second and third quarters the shuttle ispassed from right to left of the web, completing its passage at aboutthe center of the third quarter of the traverse of the lathe. Theneedles begin to rise as the lathe enters upon the fourth quarter of itstraverse, their upward movement being completed before the lathecompletes its fourth or last quarter. lathe then continues to advance tothe front to beat up the filling, and while completing the fourth orlast quarter of its course the lever L is actuated through the rod k,and the needlescarried to the left, after which the pattern-wheel isrevolved one notch or step to change the position of its pins withrespect to the bars or holders H J, ,after which the lever L iswithdrawn from the projections i of the pawls z, and striking the arms0* of said pawls disengages the pawls from the bars H J, and permits thesprings K to move the bars to the rightinto contact with thepatternwheel, and thereby change the position of the needles preparatoryto repeating the operation. The needles (I are secured to the needle baror holder H by a screw-clamp, l and the needles or in the bar J byscrews k,- but any other suitable means may be employed for thispurpose. Any desired number of needles and needle-holders may also beemployed.

Instead of using the rows of pins (1, annular cam-shaped flanges may beemployed on the wheel Q, against which the bars H J may abut, ifdesired.

The movements of the needles may be so timed as to cause them to workpick-andpick, or pass through the warp-threads at each throw of theshuttle or otherwise, as desired.

The pawls zand lever L afford a convenient means for locking the bars HJ together, and moving them away from the pattern-wheel conjointly.

A proper tension and take-up mechanism (not shown) is used with each ofthe threads 0.

But one shuttle and one reed are shown in the drawings, but it will beunderstood that The different color or colors from those composing thewarp and filling of the fabric; 'also, that in commencing the weavingthe needle-th reads should be drawn some distance through the eyes ofthe needles, in order that the loose ends of the threads may be caughtand secured in the web by the shuttle-thread.

I do not confine myself to using the loom for weaving narrow fabricsonly.

Having thus explained my invention, what I claim is 1. The lathe A,shuttle O, reed E, standards F, having boxes at, and rods T, incombination wit-h the bars H J, springs K, eye-pointed needles (I m,collar Z, pawls 2, socket f spring rod (1 lever L, rod k, apattern-wheel, devices for actuating the rods T and k, and devices forrotating the pattern-wheel, substantially as described.
